A switch this invention, the various novel features of is provided for the purpose of establishwhich will appear from the description and ing the desired connections tween the drawing forming part of this ap lication, motor-generator M and the battery B. This which discloses one embodiment 0 such inswitch may be of any type suitable for the vention, and will be particularly pointed out purpose, and is howii as comprising three i108 in t e claims. l Tn the accompanyi lFigure l is a diagrammatic view of an en- .separate bridging adapted to bridge battery terminal Bg, field ng drawings: 23a and the gear part 29 is always shaft and the crank shaft, is a one-way lThe .lever 36 is connected terminal 23h or series field terminal 22a and armature terminal Mn, and series Afield terminal 22 or armature terminal Mb and battery terminal Bb, respectively. The switch S, in one position, properly connects the motor generator for operation as a series generator supplied withv energy from the battery B, and, in another position, connects the motor-generator as a shunt wound gen-- erator for feeding the battery B.

A gear 24 is mounted on the motor shaft 21 so as to be capable of rotation relatively to said'shaft, and meshes with the gear 6 on the crank shaft 7. A clutch 25, keyed to and slidable on the motor shaft 21, is adapted to engage with a portion of the gear 24, to establish a driving connection between the motor shaft and said gear. A pinion 26 is also secured to the motor shaft.

Mounted on an intermediate shaft 27, suitably positioned adjacent both the notor riving clutch 28. This clutch is loose on the shaft 27 and capable of axial movement thereon. The clutch comprises two parts, one part 29 being provided with gear teeth to mesh with the motor pinion 26, and the other part 30 having a pinion 31, integral with or secured thereto and adapted to mesh with gear teeth 32 formed on the periphery of a portion of the ily-wheel 5. This onewaj clutch 28, may be of any suitable general type, and is here shown as one in which the parts are axially movable together and such that when the part 29 is driven by the 26, a driving connection with is made. Inthe type illustrated the part integral extension o the part 30 and is held against axial movement relativelythereto by a collar 33 on said extension. As illustrated, in mesh with the 26 on the motor shaft, but as will be be normally out of mesh with the pinion 26, and may be moved into mesh therewith by that meshes the pinion 31 with the gear teeth 32 on the ily-wheel, as these parts .are mounted for axial movement together.

The clutch 25 is operated by a lever 36 and the clutch28 is operated by a lever 37. to the operating rod 38 o the switch S, and the lever 37 is connected to a rod 39, both operating rods 38 and 39 being connected to a bell crank lever 41. The lever 41 is actuated through a rod 42 by a crank 43. This crank 43 may conveniently be loosely mounted on the shaft 17, although any construction that will permit, at times, the operation of the crank 43 when the crank 16 is operated, will suffice. In the construction illustrated, the

' crank 43 is provided with an electro-magnet 44, the core 45 of which is, in the unenergized condition of themagnet, extended by a spring or otherwise, into the path of the projection 19 of the crank 16.

1t is desirable that the crank 43 be oper- .ated to actuate the levers 36 and 37 of the switch S through the bell crank 41, only when the engine is to be started. One way this result is to have the circuit of the magnet 44 completed only when the engine is running and to withdraw the extending core 45 of the magnet 44 from the path of the projection 19 on the crank 16 when the engine is started and is driving the dynamo-electric machine M as a generator.

As shown, one side of a circuit 47, which supplies the magnet 44, is connected through a circuit 49 to one of the terminals of the machine M, and the other side of this circuit 47 is connected through a circuit 51, terminal 23 switch contact Sa, terminal Ba, and circuit 52 to the other terminal of the machine M 1t will be obvious from these connections that it will be impossible to complete the circuit of the magnet 44 eX- cept when the switch S is in generator position, and current flows in this circuit only when the machine M is operating as a generator and furnishing such current.

An electro-magnetically operated Lswitch 53 is provided which prevents the connection of the machine M, as a generator, tothe battery B to charge the same, voltage of the machine is above a predetermined value. This switch will prevent the backward flow of current when the generator voltage is lower across the batteryterminals.

Vith the parts inthe positions as shown in Fig. 1, the engine is at rest and the motorgenerator is connected as a generator, but the circuit to the battery is open at the switch 53. The circuit of the magnet 44 is connected to the machine terminals, but as the machine is inoperative to develop current, the core 45 is in its extended position, in the path o the projection 19 on crank 16. If the edal or arm 18 is moved in a clock- Wise direction, the clutch 8 is disengaged and the crank 43 is actuated through the engagement of the projection 19 with the core 45, thus actuating the bell crank lever 41, which in turn releases the clutch 25 to disconnect the gear 24 from the motor shaft and actuates the lever 37 to mesh the pinion part 31 with the gear teeth 32 on the periphery of the fly-wheel 5. The same operation of the bell crank 41 actuates the switch S to establish connections between the motorgenerator M and the battery B, such that machine M operates as a series motor su l plied with energy by the battery. As e one-way1 clutch 28 is such that when the part 29 is driven b v the pinion 26 the part 30 is operated, and as the mechanical transmission between the motor M and the crank except when the shaft 7 is such as to produce a considerable tor and the engine for establishing starting speed reduction, the engine is started in and driving connections between the -saine, operation at a considerably reduced speed. as shown in this figure, effects, successively,

The motor M will provided to close the supply circuit 84 of have had opportunity to attain its full speed magnetl 44: as soon as the machine, acting as during the retarded motion of the pedaland a generator, produces an appreciable curassociated parts, there being practically no a5 rent. 1n this way it possible to have load on the motor at this time, and when 13| y times, epecially in cold 1s a ten and other parts, to harden and even cylinder freeze.

When the under its g at hen it is apparent that the engine is operating under its own power, the pedal 18 is relieved of pressure and the spring 13 engages the clutch 8 with the clutch portion of the fly-wheel 5 and returns the edal and crank 16 to normal position. T e crank 43, being now relieved of pressure, the spring 40 acting through `the bell crank lever 41 and rod 42 returns the crank 43 to normal osition, the return movement of the piston io?) being unretarded on account of the openings 74 therein. This movement of the bell crank lever 41, due to the spring 40, operates the switch S to connect the machine M as a shunt wound generator, connects the gear 24 to the motor shaft 21 through the clutch 25, thus allowing the engine to drive the machine M through the meshed gears 6 and .24, and disengages the parts 62 and 63 and moves the same out of engagement with the gear teeth 32 and the pinion 26, respectively. Energy from the generator now closes the switch 82 and completes the circuit of the holding starting deie voltage at the generator terminals is sufficient, the switch 53 is closed,

y allowing thev generator to charge the battery B.

As it is desirable to close the circuit of the magnet 44 only when the engine is operating under its own power, it will be o Vious that a circuit direct from the battery ma be used for supplying said magnet; an means, directly responsive to the engine speed,'may be provided for closing a normally open switch in such supply circuit, when the engine attains a speed corresponding to self-actuation. A means for accomplishing this operation of the apparatus 1s shown in Fig., 3, wherein all the 'parts are similar to corresponding parts in Fig. 2, except the operating circuit for the magnet hich, instead of being closed in response to the development of sulicient voltage at the terminals of the dynamo-electric machine M, when acting as a generator, 1s

closed by a speed responsive device associated with the engine. As shown in this figure, the shaft 7 is provided with a cenl governor 91, as of the ily-ball type, the fly-ball mechanism, being slidable on the shaft 7 to projection on said sleeve to operate an arm 93 which actuates a movable switch member 94 to bridge terminal contacts 95 of a circuit 96, thusv closing a circuit including the battery B, circuit wires 84 and 8o the path of the projection 19. It will be apparent that, when the engine ceases to operate at a speed suiiicient to maintain the switch 94 in position to bridge the contacts 95, the core extension 45 will be projected into such position as to cause operation of the starting mechanism on the actuation of the clutch operating pedal 18.- However, the specific structure and location of the speed responsive device disclosed forms no part of the invention defined by this application.

As described generally inL connection with the operating circuit of the magnet 44 of 2, in case the normal circuit-closing means are ineffective to accomplish `their intended function, the circuit of the magnet 44 may be closed through the normally open switch 86.

It will be obvious that, in accordance with this invention, a starting device is provided that presents no additional control features to the operator, as, for instance, on the dashboard of a vehicle which is provided with there is no tendency toward the manual op-- the starting device when the engine is operating, and, further, there is no danger of interfering with the starting device, at any time, when the engine is running, for the only control means at hand, namely, the clutch or other operating pedal or arm, is not operatively connected to the actuating means of the starting device, at such time.
